Roller reamers can be used in hard formation or abrasive formation, in order to keep the standard hole size. When the bit size is below the standard size, it can ream the well bottom size to standard hole size. Whether drilling the vertical well or directional well, it can make the bit or casing come into the normal hole size. The features of roller reamer are small frictional resistance with well wall, strong abrasive resistance and long life.
